im am so pissed off t everyone involved, the chevy dealer i bought it from, the dealer i brought it to, and gm customer assistance . all told me im on my own. i put 900 miles on this car and paid 40k for it plus i did suspention and gears ect. un real that they can get away with this, i am debating calling the news

Mine does it at slow speeds. It's always the 1-2 shift. Thought it was me at first.

That transmission take apart sounds like a real nightmare. It is possible changing the shifter could allow them to void the warranty. They can blame the situation on the shifter and get away with not repairing your transmission.

What I might do is put my stock shifter handle on before I take it in the dealer. The Barton lets you have either.

Dealerships or shops can not perform paying work with out written permission from the customers ok, if they do then by law the customer is not responsible for any money owed! Take your receipts to your lawyer and start a suit to get your money back, dealerships should know better than that!

my issue with that is i bought the car from a chevy dealership, it had most of the work except gears and suspention already done.....thats how i bought it i had a problem and now everyone said im on my own, plus like i said #1 its a divored shifter (cable driven) so how can i have a problem with only 2 gears grinding and not all of them, #2 i stated to them at the dealer to check into the grinding noise, they ripped trans out of the car and dissasmbled...never even calling me to tell me what they were doing. and one of the first things you need to do is disconnect the shifter. so why didnt i get a call at that point to tell me , you have an aftermarket shifter and if this is shifter related you will not be covered... and # 3 the shop that is fixing it immediatly found bad syncro and gears when they went through the bin of internal trans parts the dealer left me with. how can you be allowed to take my car apart,trans, clutch,exhuaust subframe connectors and dismantle entire trans stuff all the parts into my interior, scratch and dent my car charge me storage and tell me to f#$k off.....it aint right..not to mention when the trans was hanging i now have a radiator leak, prob pulled on the hoses but still. its bs... after 3 diffrent gm reps and all the bs run around i was left to take the pieces and go find someone to put all back together

I have the 1st-2nd shift problem. I took to the dealer, they said shift slower. I called customer service, they told me to shift slower. I called Tremec they said that was GM blowing smoke. I sent a letter. They ordered my parts this week. They have a redesigned synchro, also replacing the blocker ring. Not easy to get them to do it, but you have to start with your dealer and keep moving up the chain until you get high enough for them to fix the problem.

All of the discussions are stating the same problem I am having. I have 1600 on the car and the shifts from 1 to 2 and 2 to 3 SUCK!!! My other car, a daily driver is as 5 speed stick and I have 145K on it. I definately know how to drive a stick and this trans is NOT right. I will follow your lead and go for the upgraded trans. THANKS FOR THE INTEL!!

BTW...I don't know about it in other states, but here in California if you don't SIGN the authorization to have the work performed or give verbal consent over the phone, it is ON THEM! They also have to fix the problem within the cost of the written estimate and nothing over 10% of that. In California you call the Bureau of Automotive Repair (BAR), that usually gets the dealers attention real quick.

2nd to 3rd always grinds for me until she's warmed up. I tend to shift from 2nd to 4th for the first few miles til she's ready. Not happy having to do this workaround, but i'll be visiting my local guy come springtime after she wakes from hibernation.
